Area = rectangle + triangle
A=(LxW)+(1/2 bh )
A=(20x10)+(1/2x20x4)
A=200+40
A=240
Step:6x+12y-6z+7x+7y-28z
Answer:13x+19y-34z
Answer:
1 m³
Step-by-step explanation:
first find volume of smaller cubes
V = lwh
S = 1/3*1/3*1/3
S = 1/27
find volume of large cube. there are 27 smaller cubes.
V = 27S
V = 27(1/27)
V = 1
S: volume of small cube
V: volume of large cube
(5x+2 )(x+7), i hope this helped!
It would be five times as many planes so 12*5=60 planes
